3 Command Syntax

G00 Rapid Positioning

Command Format

G00 <axis><target site>;

Argument Instruction

Axis：Specify the name of axis being shifted, and it can be any combination of X, Y, Z, A, B, C

or U, V, W. The only condition is that it must be consistent with the setting of current axis (the

4th axis is set by using the parameter #0122). The movement command for four-axis shift can

be specified for each G00 single block.

Target Site：Coordinate of the target point, which can be an absolute value or incrementalal

value in accordance with the status of G90 or G91.

Action Instruction

The function of the G00 Command can be used to enforce the tool rapid positioning to the

specified coordinate.

When G00 is used, the movement speed can not be determined by the format of F__, but it is

determined by the setting values of parameters #1000~1003, 1122~1123. The knob for fast

feedrate adjustment now can adjust the speed percentage (F0, 25%, 50%, 100%).

For the G00 movement command, the movement between servo axes is independent, and the

movement speed for each axis can be set by each parameter so that the operator should

carefully concern this situation for the avoidance of the collision of both the tool and the

workpiece. In most case, the tool axis (so-called Z-axis) should be drawn to the clearance

height before executing the G00 Command. Moreover, the activation of G00 Command can be

determined by the setting of the parameter #0041 as shown below. For more information

about the determination of the G00 simultaneous movement feedrate, refer to the following

table.

The movement speed of each axis should not exceed the G00 speed set for each axis

Dry Run Mechanism

Parameter #0083 = 0

The movement speed of each axis should not exceed the JOG speed set for each axis (Note 2)

C23 is OFF : The movement speed of each axis should not exceed the JOG speed set for each axis;

C23 is ON : The movement speed of each axis should not exceed the G00 speed set for each axis

Dry Run Mechanism

Parameter #0083 = 1



Note 1: In this case, the override is based on the fast feedrate percentage.

Note 2: In this case, the override is based on the cutting feedrate percentage.

G01 Linear Interpolation

Command Format

G01 <axis><target site> F___;


Axis：Specify the name of axis for cutting and it can be any combination of X, Y, Z, A, B, C or U,

V, W. The only condition is that it must be consistent with the setting of current axis (the 4th

axis is set by using the parameter #0122).



Action Instruction

The function of the G01 Command can be used to enforce the Tool linear cutting moving to the

position specified by the next Command from the current position with the F feedrate set.

When G01 is cutting, the actual feedrate can be adjusted by using the continuous feedrate

adjustment knob at will (0%~150%). The highest cutting feedrate can be set by using the

parameter #1004, and the actual cutting speed is the setting value of the parameter #1004

when the F value given by the maching program exceeds the setting value set by he

parameter.

X__, Y__, Z__：Coordinate of the target point, which can be an absolute value or incrementalal

value based on the status of G90 or G91.

I__：The starting point away from the center point at the X axis which is an incrementalal value

when viewing from the start point to the center point.

J__：The starting point away from the center point at the Y axis which is an incrementalal value

when viewing from the start point to the center point.

K__：The starting point away from the center point at the Z axis which is an incrementalal

value when viewing from the start point to the center point.

F__：Feedrate (mm/min or inch/min)

R__：Radius of Circular-arc

Action Instruction

G02 : Circular/Helical Interpolation Clockwise (CW).

G03 : Circular/Helical Interpolation Counterclockwise (CCW).

G02 and G03 are Commands for Circular/Helical Interpolation. Because the workpiece is 3D,

the Circular/Helical Interpolation direction on the different plane is shown in the following

diagram. The start-up default plane can be set by using the parameter #0145。The processing

command can use R to replace I, J, K directly, wherein R is the radius of Circular/Helical. If R,

I and J are written in the program, the system will take the one specified by R as a base.

For G02 and G03 Commands, the system will check and determine whether the distance from

the starting point of Circular/Helical to the center point is the same as the distance from the

end point of Circular/Helical to the center point (each one of them must be equal to the radius

of the Circular/Helical）. If the error between them exceeds 5 m, the system alarm will be

enabled【When INT 3132 uses G02/G03, the end coordinate is not on the Circular/Helical】

G09 Correct Positioning

Command Format

G09


G09 is a command that can accommodate to put off the tool. In the case of G09, each time the

system executes each positioning command, the confirmation of positioning is needed to be

taken, and the next block will be executed after confirming that the conditions of the

positioning meet the settings. If the cutting positioning occurs between blocks when operating,

the discontinuous situation will exist because of the precision demand of the positioning point,

so the speed will be sacrificed. This method will lead to the higher precision, and the

positioning precision can be set by using the parameters #0006~0009. The function of G09

can only be functioned in single block pertaining to G09, and then go back to the original

status.

case, but the G10 command can be set in maching program, and it must be set before using

these tool compensation value or G54~G59 coordinate system so that the setting values can

be activated in the maching program later.

G21;


G20：British system unit setting (inch unit), and the minimum value is 0.0001 inch

G21：Metric system unit setting (mm unit), and the minimum value is 0.001 mm

This command should be independently used, and should not coexist with other commands in

the same single block. Meanwhile, this command must be set in the header of the program, i.e.

before setting the coordinate system.

The following items must be considered when converting unit:

(1) The coordinate of workpiece should be reverted to basic system.

(2) The tool offset should be cancelled.

(3) The related parameters used in the system must be modified at the same time, and

compliant to the unit set.

G22, G23 Tool Stored Stroke Check

Command Format

G22 X___ Y___ Z___ I___ J___ K___;

G23;


X___ Y___ Z___and I___ J___ K___：Designate the range of stroke as the machine

coordinate. Please refer to the reference diagram.

Action Instruction

G23 is used to cancel the tool-stored stroke check.

G22 should be executed after manually zero point return; The tool should not enter the

prohibited stroke zone specified by G22 after the setting; otherwise the system alarm will be

triggered :

【MOT 9009 X-axis exceeds the positive stroke limit of G22】

【MOT 9010 X-axis exceeds the negative stroke limit of G22】

【MOT 9011 Y-axis exceeds the positive stroke limit of G22】

【MOT 9012 Y-axis exceeds the negative stroke limit of G22】

【MOT 9013 Z-axis exceeds the positive stroke limit of G22】

【MOT 9014 Z-axis exceeds the negative stroke limit of G22】

In the manual mode, the alarm can be disabled if user moves the servo axis in the reverse

direction; In the auto mode, the system alarm can be triggered in addition to the alarm

mentioned above【MOT 4058 exceeds the software stroke limit】, and the function of NC

is disabled, so user needs to press the RESET key to cease the alarm status.

The prohibited zone specified by G22 can be set by system parameter #0071 to determine

whether it’s an internal prohibited zone or an external prohibited zone that.

G27 Return to Origin Check

Command Format



Axis：Specify the name of axis being reverted to the origin. It can be any combination of X, Y, Z,

A, B, C or U, V, W. The only condition is that it must be consistent with the setting of current

axis (the fourth axis is set by using the parameter #0122). On the six-axes model M600,

parameters #0288 & #0289 are used to control the 5th & 6

th axes.



Action Instruction

When the program completes an operation cycle and reaches the finishing point or goes back

to starting point, G27 can be used to execute the check of “Return to origin” in order to ensure

the correctness of current actual location. After the execution of the specified stroke is

completed, G27 command will check the current position and determine whether it reaches

the mechanical origin (First reference point); if it stops at the origin after execution, the

indicator light for origin point will alight, and next single block will be run; if it does not stop at

the origin, the system alarm will be triggered【MOT 4046 “Return to origin” failed】.

When the argument X___ is specified, the Return and check could be prosecuted at the X-axis;

if not specified, the Return and check should not be prosecuted at the X-axis, and the truth

can be similarly applied to other axes.

We suggest that all Tool Compensations should be canceled before executing G27 for the

avoidance of misjudgment.

G28 Return to the First Reference Point

Command Format



Axis：Specify the name of axis being reverted to the first reference point. It can be any

combination of X, Y, Z, A, B, C or U, V, W. The only condition is that it must be consistent with

the setting of current axis (the 4th axis is set by using the parameter #0122). On the six-axes

model M600, parameters #0288 & #0289 are used to control the 5th & 6th axes.

Center point Position：Coordinate of the center point, which can be an absolute value or

incrementalal value in accordance with the status of G90 or G91.

Action Instruction

The system will preserve the coordinate of the center point specified by G28 for the further use

of G29.

In maching program, the tool can be reverted to the first reference point (machine origin) after

G28 Command is used to control the tool to pass through the center point set previously.

Before executing G28, the “manual return to origin” procedure must be prosecuted first,

otherwise the system alarm will be triggered 【“return to origin” is not yet prosecuted after the

MOT 4018 is enabled】。

When the argument X___ is not specified, return to the first reference point will not be

prosecuted at the X-axis; and on other axes as well. If no argument of any axis is specified,

G52 Interval Coordinate System Setting

Command Format

G52 <axis><origin of interval coordinate system


Axis：Specify the origin of interval coordinate system for the working coordinate system

(G54~G59) of an axis. It can be any combination of X, Y, Z, A, B, C or U, V, W. The only

condition is that it must be consistent with the setting of current axis (the 4th axis is set by

parameter #0122). On the six-axes model M600, parameters #0288 & #0289 are used to

control the 5th & 6

th axes.

Action Instruction

An interval coordinate system can be set in all manufacturing coordinate systems (G54~G59)

by using G52 Command. Sometimes this makes program coding more convenient. After G52

is set, movement commands are aiming towards the interval coordinate system set by G52

under absolute mode (G90).

Axis：Specify the name of axis being moved. It can be any combination of X, Y, Z, A, B, C or U,

V, W. The only condition is that it must be consistent with the setting of current axis (the 4th

axis is set by using the parameter #0122). On the six-axes model M600, parameters #0288 &

#0289 are used to control the 5th & 6th axes.

Target Site：Machine coordinate of the target point.

Action Instruction

G53 Command can be used to control and move the tool to the specified machine coordinate.

Regarding G53 Command, the tool’s move methoid is rapid feeding, and the speed can be set

by parameters #1000~1003, 1122~1123. Generally G53 Command belongs to “non

simultaneous movement”. If simultaneous movement is needed, it can be set by parameter

#0041. Moreover, G53 Command is effective in single block only, and it can only be used

under absolute mode (G90), it will become ineffecitve under incremental mode (G91).

Note that the previously specified Tool Compensation value will be cancelled automatically

after the execution of G53.

G61：Exact positioning mode

G61：General cutting mode.

Action Instruction

The function of G61 is the same as that of G09, but the effectiveness of G09 is limited to one

block, and the effectiveness of G61 is valid still after a declaration, until G64 (general cutting)

is declared. G64 is the default mode of the system, and the G64 mode stays effective unless

G61 is declared.

For cutting commands (G01/G02/G03), the positioning precision of each axis can be set by

using parameters #0006~0009, 0252~0253; For rapid positioning (G00), the positioning

precision of each axis is set by using parameters #0800~0830, 0268~0269. Furthermore, the

activation for the correct positioning function of each axis can be enabled or disabled by using

parameter #0043.

Command Format



P__：The macro program times to be called (Macro program name excluding the 4 digits after

“O”). The system alarm will be triggered if no input available. [INT 3111: no called program

name (no input of P address)].

L__：Times of iteration. The default setting value is 1 if no input.

In addition to arguments P and L mentioned above, more NC addresses (English alphabets excluding G, L,

N, O, P) can be used to induct arguments without any previously defined order, and these arguments are

corresponding to the local variables used in the macro program. Refer to the comparison charts listed in

G65.

Action Instruction

The difference between G66 and G65 is that the latter only calls macro program for once, but

the macro programs called by G66 will be called aincremental after each movement block is

completed until the calling mode is cancelled by G67.

In G66 blocks, G66 must be written before all arguments. Like G65, the nest type call could be

done by G66, and up to 4 levels are available for the combination of G66 and G65, (The main

program is not included, and the main program is level 0), but the G66 arguments

(corresponding to local variables of macro program) can only be set for once in G66 block,

and then the mode calling will not be reset aincremental.

G92 Coordinate Setting

Command Format

G92 <Axis><new coordinate> S__;


Axis Name：Specify the name of axis being set. It can be any combination of X, Y, Z, A, B, C

or U, V, W. The only condition is that it must be consistent with the setting of current axis

name (the 4th axis is set by parameter #0122). On the six-axes model M600, parameters

#0288 & #0289 are used to control the 5th & 6th axes.

New Coordinate Value：New coordinate value of the current tool position.

S__：Setup the maximum spindle speed. When it’s done it will replace the setting of

parameter #1096.

Action Instruction

G92 command sets up the current position as a specified coordinate, and the offset amount

between new coordinate and old coordinate will affect all coordinate systems of G54~G59.

Once G92 is set up, movement commands in absolute mode refer to the after-offset

coordinate system to calculate. To cancel the offset made by G92, one has to manually run the

zero point return procedures.

4 Indication of Auxiliary Functions (M Code)

The auxiliary functions are utilised to control of ON and OFF of mechanical functions. Format of the

command is M codes with 1 or 2 digits of number behind. M codes to be introduced hereafter belongs to

conventional auxiliary codes in controllers with fixed functions, they are not designed by specific machine

tool factory. This kind of M codes include M00, M01, M02, M30, M98, M99. Their functions are not related to

the compilation of LADDER programs.

(1) M00 ： Program Pause

When CNC executes M00 Command, the program will be paused in order to let users to proceed

dimension check, compensation and correction procedures. Press function key〈CYCLE START〉

again to restart programs after the pause.

(2) M01 ：Optional Program Pause

The function of M01 resembles that of M00, but M01 is controlled by 〈optional pause〉 key on the

panel. When the indicator light is ON, the program will be paused when program executes M01.

When the indicator light is OFF, M01 is invalid.

(3) M02 ：Program End

When CNC executes this command, the manufacturing will be ended. Press function key〈RESET〉

and then〈CYCLE START〉to continue manufacturing.

(4) M30 ：Program Ends and Cursor Returns to the Starting Point

Program ends. The function is the same as M02, but the cursor in the program check page will

return to the starting point of the progr am.

(5) M98 ： Sub-program Call

Command Format 1

M98 P__ L__;

Command Format 3

M98 H__ L__;


186



P__：Number of called sub-program (sub-program name excluding 4 numbers after “O”). If

there’s no input, the system alarm will be triggered【INT 3111 No Called Program Name (has

no P address entered)】.

L__：Times of repetition.

(6) M99 ：Sub-program ends and goes back to Main Procedure

When NC executes M99, it will return to the beginning of the program and run it again. In

sub-programs, use M99 to end the program and let it return to the main program.

The table below lists some of the M codes. Excluding M00, M01, M02, M30, M98 and M99, the others

are designed by LADDER programs with fixed functions. Such kind of M codes are not specified by

the system, and therefore might differ according to machine tool types. Users are recommended to

carefully examine command types of adopted machine tool.

5 MACRO Program

5.1 Introduction of Macro Program

Traditional NC programs have limited functions, such as being unable to operate and have no if functions.

Macro commands provide a higher level method of syntax utilization. Functions such as IF, GOTO, functions,

variables, etc. are available and bring users more flexibility.

When adopted in systems, in order to let users to call and execute a series of often-used operations with a

simple command, users can develop Macro programs to fulfill the need.

Refer to G66 command for more detail.

5.2.3 Calling Macro Programs by G Codes

Users can use G codes to call macro programs O9010~O9012 by setting parameters of #0166~0168.

Parameter #0166：G code to call macro program O9010.



When NC encounters aforementioned G codes in the manufacturing programs, it will call and execute the

corresponding Macro programs O9010~O9012. If the aforementioned parameters are set to be 0, this

function will be disabled. In the Macro programs called by G, M or T codes, G codes set by the

aforementioned parameters are considered as ordinary G codes and will be unable to call Macro programs.

When calling macro programs O9010~O9012 by the aforementioned method, users transmit numerical

values by arguments as well.

189



5.2.4 Calling Macro Programs by M Codes

Users can use M-code to call macro programs O9001~O9008 by setting parameters of #0146~0148,

0161~0165

Parameter #0146 ：M code to call macro program O9001.

respective macro programs O9001~O9008. If the aforementioned parameters are set to be 0, the function

will be disabled. In the macro programs call by G, M or T codes, the aforementioned M codes are considered

as ordinary M codes, and will be unable to call macro programs.

When calling macro programs O9001~O9008 by the aforementioned method, users transmit numerical

values by arguments as well.

5.2.5 Calling Macro Programs by T Codes

Users can use T code to call macro program O9020 by setting parameter #0169

Parameter #0169：Whether T code calls macro program O9020

If this parameter is set to be 1, T codes in manufacturing programs will call macro program O9020, and the

number following the T code will be set into system variable $149 for latter utilization. In macro programs

called by G, M or T codes, the T code will considered as ordinary T code, and will be unable to call macro

program O9020.

When calling macro programs O9020 by the aforementioned method, users transmit numerical values by

arguments as well.

5.3 Difference between Macro Program Calling (G65) and General Sub-Program Calling (M98)

1. M98 can not specify the arguments, while G65 can.

2. The level of M98 local variables is fixed, while those of G65 change according to the

nest-shaped difference of the depth. (e.g. #1 has the same meaning before and after M98, but

will differ while concerning G65.).

3. The maximum calling level of M98 and the combination of G65 and G66 are 8, while the

maximum calling level of G65 and G66 is 4.

5.5 Variables

5.5.1 Classification of Number Range

Local Variables

#01~#33 ：Read/Write

Each level og programs has 33 local variables, and they will be erased once the program ends.

However, when the RESET key is pressed, it will return to the main program level, but the content

of local variables can be specified by parameter #0141 whether or not to be erased. If the system

reboots, variables of each level all will be erased. #00 always will be an empty value.

Global Variables

@001~@999 ： Read/Write

All the levels of program utilize these variables. FANUC names them “Common Variables”.

@001~@400 will be erased when system starts or the RESET key is pressed, but @401~@999

can be controlled by parameter #0140 to determine whether or not to be the same. #00 always will

be an empty value.

System Variables

$001~$199 : Read only

$200~$399 : Read only and preserved

$400~$599 : Read/Write

$600~$799 : Read/Write and preserved

“Preserved” denotes that when the RESET key is pressed or the program restarts or the mode switches, this

variable value will maintain the same until it’s overwritten by a new value, but if the system reboots it will be

erased.
